Gracefully stopping EventMachine?
Hello all, I''ve been learning Ruby and playing with a chat server I built using GServer. After into an issue I found with GServer, that no one else seemed to notice (actually, similar to this question, GServer is hard to kill nicely, especially when you want to.), I found references to EventMachine, and rebuilt my server using it. I much prefer EventMachine''s model. The

epoll appears to break
The following program is a minor variant on the sample given in the README with eventmachine-0.8.1. I am running under CentOS 4.5 (kernel 2.6.9-55.0.2.plus.c4) with a ruby-1.8.5 RPM from the CentOS testing repository. When I run it, I find that set_comm_inactivity_timeout doesn''t do anything. That is, if I client opens a connection, it stays open indefinitely. However, if I comment out

Core dump using sample DumbHttpClient
I''m using the current release branch from the repository (version_0) on freebsd 6.1 with ruby 1.8.4. This is the error that is generated when running the code below at the bottom of the message, plus a gdb bt. Sorry no debugging symbols built into ruby but maybe the bt will help anyways. terminate called after throwing an instance of ''std::runtime_error'' what():

0-length datagram
There appears to be a problem with sending 0-length (UDP) datagrams. I have a little UDP server running on port 1392, and when I execute the following client code the server does not receive anything. However if I change it to data="x", the server receives it just fine. EM::run { conn = EM::open_datagram_socket( "", 0 ) data = "" puts

Multiple EM connections on separate threads
Hi EM Gurus, I''m hoping someone can shed some light on the following... I''m using a 3rd party (legacy) server that can accept up to 8 simultaneous connections on one port. I''ve been able to make multiple connections to this server from within one call to EventMachine::run {...}. Specificaly, I can access each connection separately using: em_thread = Thread.new do

Samba logging behavior on new files
Hi list, I have home made program, which uses File Alteration Monitor library to watch samba log files for new file creation in samba share directory. This technique works fine when I use GNU/Linux machine as client and it fails when I use Windows machine as client. The cause of failure is, samba server creates different pattern of logs and sometimes it does not create log entries on new file

EventMachine::run - How can I ensure that this
Friends, I am writing an event system which has an interface on a web site which can create events. The creation of events opens up EventMachine::run and connects to the event server, and sends messages. The problem comes if this is run inside of say, event driven mongrel, where it will crash fatally, the same as: EventMachine::run { EventMachine::run { } } The only solution that

Crash occurs where EventMachine.connect is
Hi everyone, If you subclass EventMachine::Connection and call it outside an EventMachine::run event loop, EventMachine crashes! Example: class Put < EventMachine::Connection include EventMachine::Deferrable HOST="localhost" PORT=8080 def self.request(data) EventMachine.connect(HOST, PORT, self) {|c| c.instance_eval { @data = data } } end #

epoll increasing latency big time
Sorry this is going to be a bit vague, but I''ve noticed something rather odd going on with EventMachine on Linux. I''ve written something uses EventMachine to proxy HTTP to other processes. On OS X, it works great, adding only about 20% extra latency into the connection when proxying versus connecting to the original backend process directly, so a 5ms connection might now take

Status of EventMachine.fork
Hi All, I''m currently looking into doing a bit of evented network programming in ruby and i''m currently looking into packet, eventmachine and rev. The problem is that I need to be able to fork and start a new reactor within the forked child (it also should open a socket and write status information back to the main process). I have not been able to do this with EventMachine.

How to send data,
Hello, First of all I''m new to working with sockets, so the problems I''m having are probably because of my lack of understanding. What I''m trying to accomplish is to create a mac os x client gui to ruby-debug. When a application that includes ruby-debug is started, it starts listening for 2 connections; 8989, 8990 The connection is made by calling the connectToApp

Using EventMachine to listen from non-network
I''ve actually found a way to make EventMachine listen to events from a serial port, but only by using the pure Ruby version, using Guilliame Pierronnet''s Ruby/SerialPort library. It turned out to be simpler than I thought it would be: require ''serialport'' $eventmachine_library = :pure_ruby require ''eventmachine'' module EventMachine class

undefined method `options' for #<EventMachine::HttpClien

http parser
Just thought I''d let you know that your http parser worked great for creating an http protocol handler for Eventmachine. It wouldn''t take that much effort to use Eventmachine for Mongrel, might be worth a shot just to see how it does. A few things would need to be restructered, like HttpRequest where you read the rest of the body, and calling the handler. But it

Testing event driven Socket classes
Ok, here is the class, I want to Unit Test, its part of a large app and is based on EventMachine library. I want to mock the class TickServer ( i.e not stub it) . Since in actual scenario, you can''t do this on this class: @server = TickServer.new # will toss an exception at your face you must initialize the server like this: EventMachine.run {

Interfaces for accessing SSL/TLS certificates
Hi everyone. Does anyone have any preferences or ideas for an interface for SSL certificates, both client-side and server-side? At present, the only interface is EventMachine::Connection#start_tls, which uses a built-in self-signed cert on the server side. On the cilent side, it accepts any well-formed cert (that is, it doesn''t check that the remote cert is signed by a trusted authority).

EventMachine website down?
Hi all Is the EventMachine website (www.rubyeventmachine.com) down? I can''t access it from South Africa, and have tried using tor as well with no luck. I''m kinda new to EventMachine, so I first have a lot of examples to work through and reading to do before I start pestering the mailing list with questions. Thanks to everyone who partook in creating the library, so far

ANN: EMDRb 0.1.0
I am pleased to announce the release of EMDRb version 0.1.0, a rudimentary implementation of a distributed Ruby server based on EventMachine. It''s available on Rubyforge at http://rubyforge.org/projects/emdrb but I must admit that it has thus far only been lightly tested and still a bit feature incomplete. The server implementation can already do all of the basic stuff one expects DRb
